“…We reported that STR is commonly formed of solitary cell (79.5%), while in 20.5% of the ears, it is formed of multiple cells. These results are in agreement with the results of the recent study of Hong et al [9]. STR depth in the current study was 4.17 ± 0.86 mm with a range of 2.36 to 7.85 that is near to mean detected by Marchioni et al [12] (5.1 ± 1.46 mm).…”

“…The STR is a common site of recurrent cholesteatoma, in both congenital and acquired cholesteatomas; however, it was not clearly recognized why cholesteatoma formed so easily in the STR [9]. The prevalence of residual cholesteatoma is high following mastoidectomy.…”

Background: High-resolution computed tomography (HRCT) magnifies the role of preoperative imaging for detailed middle ear anatomy particularly its hidden area. The purpose of the current study was to assess the sinus tympani (ST) and supratubal recess (STR) by HRCT, to create CT classification of the STR depth, and to study the relationship between ST types and the new STR grades. Results: In HRCT of non-pathological temporal bones of 100 subjects (200 ears), measurements of the STR and ST were calculated, registered, and analyzed. The depth of the STR was classified into grade 1 with depth less than 3 mm, grade 2 with depth ranged between 3 and 5 mm, and grade 3 with depth more than 5 mm. The mean STR length, width, and height were 4.17 ± 0.86, 3.55 ± 0.65, and 3.64 ± 0.7 mm, respectively, while the ST mean length and width of were 2.52 ± 0.5 and 1.82 ± 0.78 mm, respectively, without significant differences between either sexes or sided. The ST types were found to be type A in 56 ears (28%), type B in 142 ears (71%), and type C in 2 ears (1%). The STR grading was grade 1 in 12 ears (6%), grade 2 in 160 ears (80%), and grade 3 in 28 ears (14%) without significant relationship between ST types and STR grading (P = 0.3). Conclusion: The current study provided reliable and applicable methods of CT assessment of STR and ST that can help to predict the degree of surgical visibility of the ST and STR during ear surgery.

Background The anterior epitympanic plate (cog) and Köerner’s septum are gaining more importance since the introduction of transcanal mastoidectomy as these anatomical structures are serving landmarks for the attic. Moreover, different morphological types of cog and Köerner’s septum revealed embryological relation to the development of the isthmic membrane; the latter is linked to aeration of the attic and thus affects the pathological development of the cholesteatoma. Results A retrospective review of CT images of 86 patients proved by surgical biopsies revealed: 49 cholesteatomas and 37 non-cholesteatomatous CSOM. The type-I “cog” had a higher incidence (n = 40) and was statistically more prevalent in non-cholesteatomatous CSOM (n = 30, 81.1%). Type-II was the second commonest and was statistically more prevalent in cholesteatomatous CSOM (n = 22, 44.9%). Type-III was the third commonest, seen in (n = 18, 20.9%) and was statistically more prevalent in cholesteatomatous CSOM (n = 17, 34.7%). Köerner’s septum was more prevalent in non-cholesteatomatous CSOM (70.3%) with statistical significance (p value = 0.002). Conclusions The difference in the distribution of different morphological types of anterior epitympanic plate “cog,” as well as the difference in Köerner’s septum existence amongst cholesteatomatous and non-cholesteatomatous CSOM are suggested as risk factors for the development of cholesteatoma and may predict a cholesteatoma on CT images.

“…The eustachian tube extends between the middle ear and the nasopharyngeal cavity and provides ventilation, drainage and protection of the middle ear. The most important function of the eustachian tube is the balance between the middle ear and atmospheric pressure (6). Adenoid tissue is localized in the lymphoepithelial tissue of the nasopharynx.…”

Objective:The hypertrophic adenoid tissue can cause to eustachian tube dysfunction by mechanical or inflammatory effect both of which block the nasopharyngeal ostium of the eustachian tube. Adenoidectomy, with or without tonsillectomy, is the most common surgical procedure in children. In this study, we aimed to investigate whether nasopharyngeal irrigation for hemorrhage control in adenoidectomy patients has an effect on eustachian tube functions. Method:Patients who underwent adenoidectomy for adenoid hypertrophy evaluated on both the preoperatively and on the postoperative first day by otomicroscopic examination and with tympanometry for eustachian tube functions. Patients were divided into two groups according to nasopharyngeal irrigation type after surgery. Group 1 was the transnasal pressure irrigation group; group 2 was transoral passive irrigation group. Tympanometry was used to measure pressure, volumetric, and compliance values to compare pre-and postoperative values.Results: 40 patients were included in the study. There was no significant difference between the age and sex distributions of the patients. Volume and compliance values between the groups were similar before and after the surgery. The mean pressure values of the tympanometry parameters were highly significantly different for the right ear and moderately different for the left ear in group 1; were significantly different for the right ear and highly significantly different for the left ear in group 2.
